IMPROVEMENT IN RlCE-HULLING MACHINES.

Specification forming part of Letters Patent No. 216,633, dated June 17,187 9; application filed November 1, 1878.

To all whom it may concern:

Be it known that I, EDsELL TOTMAN, of Batavia, in the county of Kane,State of Illinois, have invented new and useful Improvements in Machinesfor Hulling Rice; and I hereby declare that the following is an exactand true description of my invention, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon.

The object of myinvention is to constructa rice-hulling machine which ischeap to build, occupies a much smaller space and requires less power tooperate than those heretoforein use, is not liable to get out of order,and will My invention consists in providing a ricehullin g machinehaving reciprocating hulling boards and arms, with oscillating arms togive a horizontal motion, and cranks to provide means for attaching themotive power, as will be more fully shown hereinafter.

Referring to the drawings, of which Figure I is a side view of myimproved rice-hulling machine, Fig. II is a plan view, Fig. III is asectional view on line a9 a, Fig. I--

A is a platform, to which is securely fastened the two standards I) and0, serving as carriers for the horizontal axle d, with cranks cl (1 Tothese cranks are journaled the arms 6 and f of the two iron frames E andF, provided with other arms, 9 and IL, respectively, which are t and k,of the oscillating arms L and M, which are fulcrum ed at l and on to theplatform A.

The axle d is rotated by aid of a belt-pulley, m.

B and 0 are the two wooden hulling boards or blocks, built up of strips42 at, one inch, more or less, in thickness, which may be dovetailed andglued to gether,or held together in any other suitable manner, or madewholly of a block of wood. These blocks or boards are held in a verticalposition, with their faces parallel to each other, by being placed inthe two frames E and F, and are therein held securely by aid 7 ofset-screws r 1', which also serve to separate or move together the facesof the blocks or boards, as may be required.

()n the outer sides and in the center of each block or board is fasteneda plate, 0 0, against the face of which the set-screws p 19, held in thestandards 8 s, are set, so that the two blocks or boards may be pressedmore or less together, as may be desired. These standards 8 s also serveto carry the funnel or hopper V,

which is pivoted to the axle w, for the purpose of raising it whenrequired.

When in position for receiving the rice the lower part of the hopperrests on the arm X.

The operation of my improved rice-hulling machine is simply as follows:The shaft (I, when rotated, gives the two rubbing blocks or boards B andG a reciprocating motion. The rice in the hopper Vdrops down through thenarrow slit o in the bottom of the hopper and falls between the saidboards or blocks, and, being hulled, drops down into a receiverunderneath the boards.

Having thus described my invention, I desire to claim- In areciprocating rice-hulling machine, the

Verticallyopposed rubbing boards clamped wi thin the frames E and F,provided with arms 6, f, g, and h, in combination with theindependently-supportin g oscillating arms L and M at one end and thedriving-cranks d and d at the other, substantially as set forth, and forthe purpose described.

EDSELL TOTMAN.
